Static Discharge Damage in a Teflon Fuel Line, ESD

Reflected Darkfield Illumination

Definition/Function:

Hydrocarbon or fluorocarbon fluids flowing through Teflon tubes can create very high static charges. In this case kerosene was flowing
through a wire-braid hose with a Teflon liner. The static charge built up on the interior of the Teflon surface and then discharged to
the wire braid on the outside of the tube. The discharge created a hole through the Teflon liner and the glass fiber insulation on the
outside of the Teflon. The result was the formation of a leak. There were a number of these discharges so the leak became significant.
